Description

  The present invention relates to a sliding door for connecting a door of a refrigeration apparatus fixed by at least one hinge to a door of a furniture body fixed by at least one single-axis or multi-axis hinge and in which the refrigeration apparatus is installed. Regarding the fixture, the slide door fixture has a guide member and a slider guided by the guide member, the guide member is disposed on one door, and the slider is disposed on the other door.

In order to design a kitchen in which the front of the furniture is uniform, it is known to install a refrigeration device with further doors in the furniture body, where the doors usually have different rotation or pivot axes.
Hereinafter, the door of the refrigeration apparatus is referred to as “apparatus door”, and the door of the furniture body is referred to as “furniture door”.
Within the scope of the present invention, “refrigerator” includes a freezer and a combination of a refrigerator and a freezer.
In addition, it is possible to use this type of sliding door fitting with other built-in household appliances having a device door, such as a microwave oven, dishwasher, steamer or oven.

For a more convenient operation, both doors are connected to each other, so that the apparatus door is opened and closed by moving the furniture door.
For this purpose, for example, from US Pat. No. 6,057,056, two doors are connected to each other in terms of their pivoting movements, and offsets of the opposite edges of the hinges of the two doors caused by different rotations or pivots are offset. Such sliding door fittings are known.

As with other kitchen furniture doors, it is also preferable to damp the closing and optionally opening actions for such built-in refrigeration doors.
Furniture doors are often dampened by dampening devices built into the hinges.
A hinge having a built-in damping device bites into the interior of the furniture body relatively large, and the installation space for the refrigeration device in the furniture body is reduced. Therefore, such a hinge is a door of the furniture body for the built-in refrigeration device. This is inconvenient.

A refrigeration device and / or freezer suitable as a built-in device into the furniture body is known from US Pat.
In this device, an attenuation device is incorporated in the door of the refrigeration device.
However, it is preferable that a refrigeration apparatus without such a built-in attenuation device is also provided with attenuation performance.

From Patent Document 3, a damping device is known which is arranged in addition to a sliding door fixture between a furniture door and a device door.
However, a depth is required to install this damping device, and in order to make the gap between the refrigerator door and the furniture door as small as about several millimeters, a recess is provided in the refrigerator door. It will be necessary.
Therefore, it becomes impossible to use this configuration universally or retrofit it.
Furthermore, the additional damping device increases the installation effort when installing the refrigeration device in the furniture body.

European Patent Application No. 0565900 (A1) specification European Patent Application No. 2314962 (A1) Specification International Publication No. 2011-101319

  The object of the present invention is that the door of the furniture body and the door of the refrigeration apparatus are connected to each other, and the installation space for the refrigeration apparatus in the furniture body is reduced by the attenuation function without special design. Instead, it is to provide a structure of the refrigeration apparatus in the furniture body in which the attenuation of the operation of both doors is achieved.

This problem is first solved by a sliding door fixture having the features of the independent claim 1.
Advantageous embodiments and improvements of this sliding door fitting are the subject of the dependent claims.

  A sliding door fixture of the kind described above according to the invention is characterized in that it has at least one damping device for damping the relative movement between the slider and the guide member with at least one predetermined part of the relative movement. To do.

Incorporating the dampening device into the sliding door fixture provides a compact structure in the connection of the two doors, while also providing dampening of the opening and / or closing movements.
This slide door fixture can be used universally or retrofitted to commercial refrigeration equipment, as well as known fixtures used only for door connection.

In a preferred embodiment of the sliding door fixture, the slider is guided in a sliding bearing guide by a guide member.
This allows for a simple and cost effective construction of the sliding door fixture.

In another preferred embodiment of the sliding door fixture, a plurality of damping devices are provided, which are arranged adjacent to each other in the guide member or on the guide member or in the slider or on the slider.
By distributing the damping operation to a plurality of damping devices, it is possible to use the flattest damping device.
By arranging them adjacent to each other, the installation height of the slide door fixture can be kept low correspondingly.

In yet another preferred embodiment, the sliding door fixture has at least one energy accumulator, which is arranged to be loaded by opening and / or closing of the doors connected by the sliding door fixture. ing.
The at least one energy accumulator preferably applies a force on the guide member to the slider from a specific opening / closing angle of the door.
Furthermore, the at least one energy accumulator is preferably operatively connected directly or indirectly to the at least one damping device and applies a force to the damping device in the direction of damping.

In a further preferred embodiment, the sliding door fixture has at least one carrier, which cooperates with at least one energy accumulator.
In this case, the transport body can be guided by the control member, wherein the control member is provided in the guide member or on the guide member, and the transport body and the slider are moved over at least a part of the relative movement. An engaging or control member is provided in or on the slider, and the carrier is engaged with the guide member over at least a portion of the relative motion.
The at least one transport body is preferably mounted so as to be pivotable about an axis that is substantially perpendicular to the front surface of any one of the doors.

The door is provided with an automatic closing function, or the closing operation of the door is assisted by the accumulator.
This simplifies the operation of the door of the refrigeration device and ensures that the device door is closed which is important in the function of the device.

In another preferred embodiment of the sliding door fixture, at least one further damping device is provided for damping the relative movement between the slider and the guide member, which is relative to the damping direction of the damping device. Damping movement.
Thus, the door is not only attenuated during the closing operation, but is also attenuated when opening up to the maximum opening angle.
It is possible to avoid excessive extension of the hinges and a door hitting a wall, for example.

In yet another embodiment of the sliding door fixture, the at least one damping device and / or the at least one further damping device is a linearly actuating device having a cylinder and a lift rod.
In another preferred embodiment, the at least one damping device and / or the further damping device is a rotary damper, the slider having a push rod which is at least partly configured as a toothed rod.
In any of these configurations, the linear movement operation of the slider with respect to the guide member can be attenuated.
In any configuration, the flat configuration of the attenuation device is possible.

In yet another preferred embodiment of the sliding door fixture, the transport plate is arranged to be pivotable at one end of the slider or is flexible and the transport plate is angled at the end. The slider has a push rod arranged.
Due to the different pivoting axes of the two doors, the equipment door and the furniture door, the free ends of the door not only move relative to each other when opening and closing the door, but also slightly pivot relative to each other.
This swiveling is made possible by the above-mentioned swivelable transport plate or a flexible push rod having a sufficient length.

In a further preferred embodiment, the sliding door fixture has at least one adjustment device for at least one adjustment range.
Such an adjustment range depends on the embodiment, in particular the magnitude of the damping action and / or the magnitude of the accumulator action and / or the relative position between the slider and the guide member where the damping action starts. It is.
The opening and closing speed of the doors to be connected and / or the opening and closing angle of the door where the automatic pull-in operation starts can also be adapted to the individual requirements and the refrigeration system in this way.

  The invention is explained in more detail below on the basis of exemplary embodiments with reference to the drawings.

FIG. 1b is a detailed view of FIG. 1a. FIG. 1b is a diagram of a state in which the sliding door fixture of the furniture body having the built-in refrigeration apparatus shown in FIG. 1a is completely installed. FIG. 2b is a detailed view of FIG. 2a. It is a top view of the slide door fixture of the state from which the cover was removed. FIG. 3b is a top view of the sliding door fixture with the slider in a different position than in FIG. 3a and the cover removed. FIG. 4 is a top view of the slide door mounting tool with the slider at a different position from that of FIGS. 3a and 3b and with the cover removed.

(Embodiment 1)
FIG. 1 is a schematic perspective view of the furniture main body 10 in a state in which the furniture door 11 fixed to the side wall of the furniture main body 10 via, for example, two hinges 13 is opened.
A refrigeration apparatus 20, such as a refrigerator or a freezer, is installed in the furniture body 10.
The refrigeration device 20 has a device door 21 which is here closed.

A sliding door fixture according to the present application is installed in the region of the free edge 12 of the furniture door 11.
The slide door fixture includes a guide member 30 fixed to the furniture door 11 and a slider 40 that is movable relative to the guide member 30 and guided by the guide member 30.
FIG. 1 a shows a state in the middle of installation in order to show the installation of the sliding door fixture in the furniture door 11.

FIG. 1b shows in greater detail the area of the sliding door fitting of FIG. 1a.
The guide member 30 has a cover 31 having a fixing hole 32, and the slide door mounting tool is screwed to the furniture door 11 through this hole.
The guide member 30 is implemented as a plate having a substantially rectangular bottom surface, whereby the guide member 30 is arranged on the surface of the furniture door 11.
Perpendicular to this bottom surface, the guide member 30 has a low installation height of a few millimeters to about 10 mm.

The slider 40 includes a push rod 41 that is aligned in parallel with the bottom surface of the guide member 30, and a transport plate 42 that is substantially perpendicular to the push rod 41 is attached to a free end thereof.
The transport plate 42 and the push rod 41 are not firmly connected to each other, but are connected by a hinge formed by a pin that connects the push rod 41 and the transport plate 42.
The angle between the push rod 41 and the transport plate 42 can be changed within a certain angle range by the hinge.

FIG. 2a shows the refrigeration apparatus 20 installed in the furniture body 10, similar to FIG. 1a, but here the sliding door fixture is in a fully installed state.
The furniture door 11 and the device door 21 are connected to each other by a sliding door fixture in the region of the respective pivotable free edge 12 or 22 opposite the hinge of the door 11, 21.
In the illustrated embodiment, both doors 11, 21 are open.
The hinge supporting the device door 21 of the refrigeration apparatus 20 is often a pin hinge, but is not visible in this view.

FIG. 2b shows details of the area of the sliding door fitting of FIG. 2a, similar to FIG. 1b.
It is clear that the transport plate 42 is on the free edge 22 of the device door 21 and is connected thereto, for example by a screw connection.
Opening the furniture door 11 or the device door 21 causes a relative movement of the free edges 12 or 22 of each of the two doors 11, 21, thereby causing movement on the one hand and 2 on the other hand. A slight swiveling of the two edges 12, 22 occurs.
The swiveling of the two edges 12 and 22 with respect to each other is offset by the tilting property of the transport plate 42 with respect to the push rod 41.
Due to the movement of the edges 12 and 22 relative to each other, the slider 40 moves relative to the guide member 30.
Thus, in FIG. 2b, the slider 40 is pushed into the guide member 30 out of its rest position as seen in FIGS. 1a and 1b.
Such movement to the guide member 30 is made possible by the corresponding recesses in the cover 31, although there is a transport plate 42 protruding at an angle.

Figures 3a to 3c show in more detail an exemplary embodiment of a sliding door fitting according to the present application.
In order to show the internal structure of the slide door fixture, the slide door fixture is shown without the cover 31 in these three figures.

3a, 3b, and 3c, the position of the slider 40 with respect to the guide member 30 is different.
FIG. 3a shows the slider 40 of the sliding door fixture in a rest position, which is also shown in FIGS. 1a and 1b.
FIG. 3 c shows the end position of the slider 40 where the slider 40 is pushed into the guide member 30 as much as possible.
FIG. 3b shows the central position of the slider 40 between the rest position of FIG. 3a and the end position of FIG. 3c.

The guide member 30 has a base plate 33 on which the cover 31 shown in FIGS. 1b and 2b is arranged.
Therefore, the fixing hole 32 implemented as an elongate hole is provided in the base plate 33 in the same position as the cover 31 here.
The cover 31 can be locked with the base plate 33.
In the installed state, it is additionally held by a common fixing screw.
The base plate 33 can be integrally manufactured, for example, as an aluminum or zinc die cast part or a plastic injection molded part.

A guide portion 34 aligned in the longitudinal direction of the base plate 33 is provided in the base plate 33 as, for example, a dovetail joint or a T-groove type sliding support guide.
The guide portion 34 is disposed in the center with respect to the lateral direction of the base plate 33.
The slider 40 is inserted into the guide part 34 with a push rod 41 adapted to the shape of the guide part 34.

The push rod 41 moves to a hammer-shaped head 43 in a T-shape at the end of the guide member 30 facing the transport plate 42.
This head 43 interacts with the lift rod 36 of the damping device 35 shown only in FIG. 3a.
The damping device 35 can be, for example, an air or fluid damping device.
Here, four damping devices 35 are provided, which are arranged in two pairs, symmetrically adjacent to the guide 34.
Basically, it is possible to provide other numbers of attenuation devices 35.
The plurality of attenuation devices 35 arranged adjacent to each other have an advantage that a sufficient attenuation effect can be obtained even when the structural height of the sliding door fixture is low.

In the illustrated embodiment, a known cylinder damper that operates linearly is used as the damping device 35.
The lift rod 36 receives a slight spring load and presses the head 43 so that the head can move from the rest position shown in the drawing to the end position (to the left in the drawing) without a damping operation.
In the reverse movement to the rest position, the damping action of the damping device 35 starts when the head 43 hits the free end of the lift rod 36.
In the embodiment illustrated here, the stroke of the lift rod 36 is less than the travel distance between the rest position and the end position of the slider 40.
Thus, the damping is not performed over the entire distance, but only in the part before the rest position defined by the stroke of the lift rod 36.

A certain amount of play can be provided in the guide 34, which gradually increases towards the edge region of the base plate 33.
Thus, the push rod 41 has play in a direction perpendicular to the guide direction and parallel to the base plate.
If the rotation or swivel axes of the furniture door 11 and the device door 21 do not extend exactly parallel to each other, this means that the edge 22 of the device door 21 is at the height of the furniture door 11 when the doors 11, 21 are swiveled. It will shift | deviate with respect to the edge part 12.
Such an operation can be canceled by the play of the push rod 41 described above.

Further, two control members provided here as hook-shaped curved portions 37 are incorporated in the base plate 33.
The transport body 38 moves within each control member.
The conveyance body 38 has recesses facing each other, and the head portion 43 of the slider 40 is engaged with the extension portion thereof.
Hereinafter, this portion is referred to as a starting member 44.
Further, here, a power accumulator implemented as a spring 39 is assigned to each carrier 38.
The spring 39 is configured as a tension spring, and is fixed to the transport body 38 at one end, and is fixed to a fixing point of the base plate 33 at the other end, whereby the slider 40 is moved by the starting member 44 and the transport body 38. Pulled to the rest position.
Here, the spring 39 can be preloaded in the rest position.

FIG. 3 b shows the sliding door mounting portion at the position of the slider 40 corresponding to the opening angle of about 50 ° of the doors 11, 21.
An opening angle of 0 ° is a state in which the doors 11 and 21 are closed, and an opening angle of about 90 ° is a state in which the doors 11 and 21 are opened at a right angle.

In FIG. 3 b it can be seen that the lift rod 36 of the damper 35 has already been fully extended and has not pressed the head 43.
On the other hand, the guide head of the transport body 38 almost reaches the end of the hook-shaped curved portion, and the left end of the receiving opening that cooperates with the starter member 44 is already engaged with the starter member 44 in the drawing. It can also be seen that they are far away from each other.
Therefore, the slider 40 can further move in the direction of the terminal position without receiving further load on the tension spring 39.

Due to the shape of the hook-shaped curved portion 37 and the location where the force of the spring 39 in the cantilever arm of the transport body 38 is applied, this arm remains in the end of the hook-shaped curved portion 37.
This is shown in FIG. 3c where the slider 40 is in the end position.

This end position is not necessarily reached when the sliding door fixture is used.
However, the sliding door fixture must be sized so that the desired maximum opening angle of the furniture door 11 and device door 21 is obtained by the distance traveled.
It is conceivable that the maximum opening angle of the doors 11 and 21 is defined by the end position of the sliding door fixture.
However, the maximum open position can also be determined by the hinge 13 of the furniture body 10 or the hinge of the refrigeration apparatus.

When the doors 11 and 21 are closed, the slider 40 first moves in the direction of the rest position (to the right in FIGS. 3a to 3c).
When passing through the central position shown in FIG. 3b, the transport body 38 first moves out of the end position of the hook-shaped curved portion 37, and at that time, the tensile force of the spring 39 is applied to the transport body 38 and the slider 40, An automatic closing function of the doors 11 and 21 is provided.
When further closed, the head 43 is placed on the end of the lift rod 36 of the damping device 35, thereby being damped to the rest position of the refrigeration device and closed.

(Embodiment 2)
In another embodiment of the sliding door fixture, in addition to the damping function when the furniture door 11 or the device door 21 is closed, it is also conceivable that the door 11, 21 is attenuated when moved to the maximum opening angle.
For this purpose, one or more further damping devices can be arranged in the guide member 30 in the opposite end region of the base plate 33 in addition to the damping device 35, where the head 43 is brought into the terminal position. Hit when moving.
This further damping device can also be implemented as an air or fluid damping device, for example.
The additional damping device can also be implemented as a flexible member, since the distance attenuated when the door 11, 21 is moved to the maximum opening angle can be very small.

(Embodiment 3)
In another embodiment of the sliding door fixture, the linearly acting damping device 35 shown in FIGS. 3a to 3c may be provided as one or more rotary dampers.
For this purpose, the push rod 41 can be implemented as a toothed rod, for example.
A rotary damper to which a gear cooperating with the gear teeth of the push rod 41 is attached is disposed in the base plate 33.
In this case, it is conceivable that the teeth are provided only partially on the push rod 41 so that the attenuation is performed only at a predetermined moving distance within the region of the rest position.

(Embodiment 4)
In yet another embodiment of the sliding door fixture, the length of the push rod 41 is such that the transport plate 42 is located outside the bottom surface of the guide member 30 and is above the base plate 33 over the entire travel path of the slider 40. Can be implemented long enough so that they are not placed directly.
Therefore, the cover 31 does not need to have a notch on the upper side, and may have a recess for a push rod on the side.
In this embodiment, the guide member 30 can be completely hidden between the furniture door 11 and the apparatus door 21 and is not visible when the doors 11 and 21 are opened.
Furthermore, if the push rod 41 is configured to be slightly flexible, the pivoting of the edges 12 or 22 of the two doors 11, 21 with respect to each other during the opening operation is offset by the long flexible push rod 41. Therefore, the turning property of the transport plate 42 with respect to the push rod 41 can be omitted.
The transport plate 42 can then be implemented integrally with the push rod 41, for example as a plastic injection molded part.

(Embodiment 5)
In yet another embodiment of the sliding door fixture, an adjustment device can be provided that allows adjustment of the damping operation of the at least one damping device 35.
If the damping device 35 is implemented as an air or fluid damping device, the adjustment of the damping operation can be done in a known manner, for example using a throttle screw.
With this adjusting device, it is possible to adjust, for example, the closing and / or opening speed of the cooperating doors 11, 21.
This may be necessary when retrofitting to existing built-in home devices and furniture body doors.

(Embodiment 6)
In yet another embodiment of the sliding door fitting, the accumulator acting on the at least one damping device 35, i.e., for example, the closing and / or opening force of the spring 39 is adjustable, thereby closing and / or opening. An adjustment device can be provided that allows the speed to be adjusted.
This can be done, for example, by adjusting the length of the spring 39 with an adjusting screw or worm gear.
For example, if the accumulator is implemented as a coil spring, it is possible to wind up the coil spring more or less by the adjusting device for the change of force.

(Embodiment 7)
In yet another embodiment of the sliding door fitting, an adjustment device can be provided that can change the closing and / or opening angle at which the damping action of at least one damping device 35 begins.
In the illustrated embodiment, a locking hole 32 configured as an elongated hole is shown as such a simple adjustment device.
An adjustment device is also conceivable which is operable after the sliding door fitting is fixedly screwed onto one of the doors.
For example, it is conceivable that at least one damping device is moved to a corresponding position by means of a worm gear or an adjusting screw.
Alternatively or additionally, it is conceivable that the relative position of the means for starting at least one damping device 35, for example the head 43 of the slider 40, relative to the damping device 35 is changed in the sliding door fixture.
For this purpose, for example, at least one damping device 35 can be arranged to be movable relative to the guide member 30 within the sliding door fixture, so that the head 43 of the slider 40 At various positions of the slider 40, it is arranged at the end of the lift rod 36 of the damping device 35.

The adjustment device described above acts on at least one adjustment range of the sliding door fixture.
Depending on the embodiment, this adjustment range is in particular the magnitude of the damping action and / or the magnitude of the accumulator action and / or the relative position between the slider and the guide member where the damping action starts. .

  Here, the sliding door fixture has been described in relation to the refrigeration system, but it can be used in other built-in household devices that are installed in the furniture body with furniture doors and have individual device doors. Is self-explanatory.
